Answer 1

How to set a port limit?

Answer 2

Depending on what speed, 1gb 100mb.s can be easily done by switching the port to the desired mode.
If you need to shape the other one here, you can do it on your equipment (it will be more correct), but many providers put a microtic on the client, for example, they shape it already on it, so they reduce the load on their switch (router), but make an extra point of failure at client.
